UVS Play Mode results — compare
Compares baseline Registry 1.9.11 vs candidate enhanced using the latest matching XML files in TestResults/.
Prerequisites
Both runs must exist:
uvs-playmode-tests-registry (or Run-UvsPlayModeBenchmarks.ps1 -UvsSource Registry)uvs-playmode-tests-enhanced (or -UvsSource EnhancedGit)
Compare (default: latest Registry vs latest EnhancedGit)
.\tools\Compare-UvsPlayModeResults.ps1
Equivalent:
.\tools\Compare-UvsPlayModeResults.ps1 -BaselineSource Registry -CandidateSource EnhancedGit
Compare explicit files
.\tools\Compare-UvsPlayModeResults.ps1 `
-BaselineXml "TestResults\playmode-Registry-20260525-100000.xml" `
-CandidateXml "TestResults\playmode-EnhancedGit-20260525-103000.xml"
Other pairs
# Stable promoted fork vs enhanced integration
.\tools\Compare-UvsPlayModeResults.ps1 -BaselineSource StableGit -CandidateSource EnhancedGit
Output
- Markdown printed to the terminal
- Saved to
TestResults/compare-<baseline>-vs-<candidate>-<timestamp>.md
Sections:
- UVS tests — median ms, Δ ms, Δ % (negative Δ % = candidate faster)
- C# sanity check — should stay near 0% change if only UVS changed
- UVS/C# ratio change — script overhead vs C# ceiling
How to interpret for the user
| Observation | Meaning |
|---|
| UVS Δ % negative at high N | Enhanced fork faster than Registry |
| UVS Δ % near 0 | Little measurable difference in this environment |
| C# Δ % large | Environment unfair or non-UVS change; re-run |
| Ratio drops | UVS closer to C# ceiling |
Lead with UvsCounter and UvsOverhead at N=1000 and 5000.
Full workflow (agent checklist)
- [ ] Run Registry benchmarks
- [ ] Report Registry (optional): Report-UvsPlayModeResults.ps1 -Source Registry
- [ ] Run enhanced benchmarks
- [ ] Report enhanced (optional): Report-UvsPlayModeResults.ps1 -Source EnhancedGit
- [ ] Compare-UvsPlayModeResults.ps1
- [ ] Summarize comparison markdown for the user
Troubleshooting
| Issue | Action |
|---|
| No baseline XML | Run Registry tests first |
| No candidate XML | Run enhanced tests first |
| Missing median values | Inspect XML test output; re-run tests in Unity 6000.4 |
